Quackery, often synonymous with health fraud, is the promotion of fraudulent or ignorant medical practices. A quack is a "fraudulent or ignorant pretender to medical skill" or "a person who pretends, professionally or publicly, to have skill, knowledge, qualification or credentials they do not possess; a charlatan or snake oil salesman". The term quack is a clipped form of the archaic term quacksalver, from Dutch: kwakzalver a "hawker of salve". In the Middle Ages the term quack meant "shouting". The quacksalvers sold their wares at markets by shouting to gain attention.
Orthomolecular medicine is a form of alternative medicine that aims to maintain human health through nutritional supplementation. The concept builds on the idea of an optimal nutritional environment in the body and suggests that diseases reflect deficiencies in this environment. Treatment for disease, according to this view, involves attempts to correct "imbalances or deficiencies based on individual biochemistry" by use of substances such as vitamins, minerals, amino acids, trace elements and fatty acids. The notions behind orthomolecular medicine are not supported by sound medical evidence, and the therapy is not effective for chronic disease prevention; even the validity of calling the orthomolecular approach a form of medicine has been questioned since the 1970s.
Therapeutic touch (TT), or non-contact therapeutic touch (NCTT), is a pseudoscientific energy therapy which practitioners claim promotes healing and reduces pain and anxiety. "Therapeutic Touch" is a registered trademark in Canada for the "[s]tructured and standardized healing practice performed by practitioners trained to be sensitive to the receiver's energy field that surrounds the body;...no touching is required."
Craniosacral therapy (CST) or cranial osteopathy is a form of alternative medicine that uses gentle touch to feel non-existent rhythmic movements of the skull's bones and supposedly adjust the immovable joints of the skull to achieve a therapeutic result. CST is a pseudoscience and its practice has been characterized as quackery. It is based on fundamental misconceptions about the anatomy and physiology of the human skull and is promoted as a cure-all for a variety of health conditions.
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. Chelation therapy has a long history of use in clinical toxicology and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of mercury and other metals through the brain and other parts of the body by the use of weak chelating agents that unbind with metals before elimination, exacerbating existing damage. To avoid mobilization, some practitioners of chelation use strong chelators, such as selenium, taken at low doses over a long period of time.
Essiac is a herbal tea promoted as an alternative treatment for cancer and other illnesses. There is no evidence it is beneficial to health. In a number of studies Essiac either showed no action against cancer cells, or actually increased the rate of cancer growth.
Chromotherapy, sometimes called color therapy, colorology or cromatherapy, is an alternative medicine that is considered pseudoscience and quackery. Chromotherapists claim to be able to use light in the form of color to balance "energy" lacking from a person's body, whether it be on physical, emotional, spiritual, or mental levels. For example, they thought that shining a colored light on a person would cure constipation. Historically chromotherapy has been associated with mysticism and occultism.
Max Gerson was a German-born American physician who developed the Gerson Therapy, a dietary-based alternative cancer treatment that he claimed could cure cancer and most chronic, degenerative diseases.
Metabolic typing is considered by some a pseudoscience whose proponents believe that each person has a unique metabolism, and that the proportion of macromolecules which are optimal for one person may not be for a second, and could even be detrimental to them.
William Donald Kelley was an American orthodontist who developed "non-specific metabolic therapy," an alternative cancer treatment, now known to be ineffective, which he based on his personal belief that "wrong foods [cause] malignancy to grow, while proper foods [allow] natural body defenses to work."
714-X, also referred to as 714X or trimethylbicyclonitramineoheptane chloride, is a mixture of substances manufactured by CERBE Distribution Inc and sold as an alternative medical treatment which is claimed to cure cancer, multiple sclerosis, fibromyalgia and other diseases. There is no scientific evidence that 714-X is effective in treating any kind of cancer, and its marketing is considered health fraud in the US.
Alkaline diet describes a group of loosely related diets based on the misconception that different types of food can have an effect on the pH balance of the body. It originated from the acid ash hypothesis, which primarily related to osteoporosis research. Proponents of the diet believe that certain foods can affect the acidity (pH) of the body and that the change in pH can therefore be used to treat or prevent disease. However, their claims are false, and there is no evidence supporting the claimed mechanisms of this diet, which is not recommended by dietitians or other health professionals.
Hoxsey Therapy or Hoxsey Method is an alternative medical treatment promoted as a cure for cancer. The treatment consists of a caustic herbal paste for external cancers or a herbal mixture for "internal" cancers, combined with laxatives, douches, vitamin supplements, and dietary changes. Reviews by major medical bodies, including the U.S. Food and Drug Administration (FDA), the National Cancer Institute, the American Cancer Society, M. D. Anderson Cancer Center, and Memorial Sloan-Kettering Cancer Center, have found no evidence that Hoxsey Therapy is an effective treatment for cancer. The sale or marketing of the Hoxsey Method was banned in the United States by the FDA on September 21, 1960 as a "worthless and discredited" remedy and a form of quackery.
Luigi Di Bella was an Italian medical doctor and physiology professor. In the late 1980s, he created a purported treatment known as "Di Bella therapy" for cancer that precipitated an international controversy.
Alternative cancer treatment describes any cancer treatment or practice that is not part of the conventional standard of cancer care. These include special diets and exercises, chemicals, herbs, devices, and manual procedures. Most alternative cancer treatments do not have high-quality evidence supporting their use and many have been described as fundamentally pseudoscientific. Concerns have been raised about the safety of some purported treatments and some have been found unsafe in clinical trials. Despite this, many untested and disproven treatments are used around the world.
Energy medicine is a branch of alternative medicine based on a pseudo-scientific belief that healers can channel "healing energy" into a patient and effect positive results. The field is defined by shared beliefs and practices relating to mysticism and esotericism in the wider alternative medicine sphere rather than any sort of unified terminology, leading to terms such as energy healing or vibrational medicine being used as synonymous or alternative names. In most cases there is no empirically measurable energy involved: the term refers instead to so-called subtle energy. Practitioners may classify the practice as hands-on, hands-off, and distant where the patient and healer are in different locations. Many schools of energy healing exist using many names: for example, biofield energy healing, spiritual healing, contact healing, distant healing, therapeutic touch, Reiki or Qigong.
Neural therapy is a form of alternative medicine in which local anesthetic is injected into certain locations of the body in an attempt to treat chronic pain and illness.
Black salve, also known by the brand name Cansema, is an ineffective and unsafe alternative cancer treatment. The product is commonly classified as an escharotic—a topical paste which destroys skin tissue and leaves behind a scar called an eschar. Escharotics were widely used to treat skin lesions in the early 1900s, but have since been replaced by safer and more effective treatments. Escharotics, such as black salves, are currently advertised by some alternative medicine marketers as treatments for skin cancer, often with unsubstantiated testimonials and unsupported claims of effectiveness.
The Oasis of Hope Hospital is a clinic in Tijuana, Mexico providing alternative cancer treatments to its customers. The clinic was founded by the physician Ernesto Contreras. After his death in 2003, the management of the hospital was taken over by his son, Francisco Contreras, and nephew, Daniel Kennedy.
Grape therapy or grape diet, also known as ampelotherapy, is a diet that involves heavy consumption of grapes, including seeds, and parts of the vine, including leaves, that is a form of alternative medicine. The concept was developed in the 19th century Germany in spas, like Bad Duerkheim or Merano. The concept has no scientific basis and is regarded as quackery by scientific institutions like the American Cancer Society.
